FORNIA.

- Application filed October. 1

'Beit known that I, WILLIAM T. FLEMING, a citizen-of the United States, residing atLos Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Roller-Bearings, of which the following is a specification.

My invention relates to improvements in and in the means for assembling. and holding therollers together; and the object thereof is to provide, a rollersbearing in which the bearing-rollers will be evenly held and in' which the" parts can be united together and handled asa unitary body. y

In the drawings forming a part of the application I have illustrated my invention as aelplied to an axle and wheel,,the box of the w eel only being shown; but my invention is equally applicable to bearings where one part'is rotatable Within'or exterior to the other part.

, Upon the end of the axle 5 is mounted a sleeve 6. A key-seat 7 is provided in the axle, and in the sleeve is a keyway 8. In this ke -seat is mounted a key-.9, which -prea vents t e sleeve from rotating upon the axle.

Near each end the sleeve is rovlded with,an-

nular'flanges wand 11, w"ch form guides.

These: grooves are deep enough to prevent the spacing-rollers from having an endwise inotion, but not-deep enough to permit the body of the spacing- The bearingrollers 14 are provided near the ends thereof with grooves 15,-which straddle the flanges of the sleeves. These rooves are so deep that within the grooves t 1e necks of the bearing-rollers do not touch the flanges. The bearing-rollers have a gt'eater diameter than ose portions thereof whichbear against the sleeve'and the hub 16 of the wheel, while those portions of the bear- Specification of Letters Patent.

ROLLER-BEARING...

. spacer'rollers do engage the flan es within the grooves at the ends thereof. These flanges form supporting-tracks for the suportlng-rollers and guides for both rollers. urrounding these rollers and within the grooves at the" ends thereof are the asse1n- .bling and holding rings 17 which engage with the necks of the spacing-rollers within their hearing-rollers within their grooves.

, In order to assemble the arts, I cut apertures 18 at each end of the s leeve, which also cuts away a portion of the flanges, removing to insert a bearing=roller between the sleeve and the holding-rings when the holding-rings ertures as far as they can go. "I first lace with theirend grooves inclosing the holdin I then slip as aci'n -roller throug the cut-away portion 0 the anges and drop roller. "then slip another spacing-roller through this cut-away portion of the fla es andbring it to the same side as the ot er spacing-roller andthen'bring a bearing-roller over onto of it and repeat the operation .I' then insert from the inside of the sleeve into eachaperture the sleeve an insertible fla e-section .19, which is of such shape as to fi l the-aperture in the sleevefland. to com- .'plete the flanges on the sleeve. screw/'20 1 asses into the sleeve at each end and slightly 'into' section 19, a small hole 19 being provided therefor soas to prevent the same "from fall' out. The sleeve and rollers are the axle and is held in place thereon by the retain' -nut 23. i I

By this construction a roller-bearing is provided whic thenilplac e the hub and held therein by means of screw dust-caps 21 and 22 at each end thereof. .The sleeveis then slipped upon can be handledgas a unitary body-, and 1ii which the bearing-rollers are rooves and are free from the necks of the 'so much thereof as is necessary to enable me are pushed upwardly and away -from said apall of the bearing-rollers upon the s eeve the same' down at one side thereof'and bring a bearing-roller over torest' on this spacing- I until all 0 the spacing-rollers are m place.

, secured to ft evenly held apart by the spacing-rollers, and in which the spacing-rollers are held from contact with the outer member and from contact with the inner member except within the grooves at the ends of the spacing-roller, thereby providing a superior roller-bearing.

In themodification shown in Figsalz and 5 the sleeve is dispensed with and the guiding and supporting tracks for the ends of the rollers consist of rings 24, which are provided with removable sections 24, which may be he main portion of the ring by means of ddiwel-pins 25. In this construction the reii-iearable section of the inner ring or guide-traclrlis removed and the supporting and spacingiollers are placed alternately be tween the track-ring 24 and the holding or assembling ring 27, which is of the same character and construction and performs the same function as rings 17 in the construction shown in the other figures. After the last roller is placed between the track-ring 24 and the assembling-ring 27 the removable sections of the track-rings are secured in place andithe rollers and rings slipped within the hub 28 and the dust-caps 29' and 30 screwed thereon. The hub is then slipped upon theaxle 31 and is held in place by the usual retaining-nut 32.

To' revent anylongitudinal movement 'of v the ro lers within the hub, the outer end of the axle is reduced and a collar33, provided with a removable section .33, is placed on the reduced portion of the axle and is held inplace thereon by the-usualretaining-nut 32. This collar is provided'with a track-ring 34; which is m'ad'e'integral therewith, and the removable section 33 is held in place by the screw 35.

Having described. my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A roller-bearing comprising bearing'and spaci'm rollers alternately arranged, each of' saic. rollers having grooves near the ends thereof, one groove at each end, the grooves in the bearing-rollers being deeper than those in the spacing-rollers and the bodies of the bearing-rollers within the grooves being oi less diameter than the bodies of' the spacing-rollers within their grooves and of greater diameter than the spacing-rollers e);- cept at the grooves; holding-rings within the oldin -rings engaging the bodies of the spacgrooves onthe outer sides of-said' rollers, said ing-r01 ers Within the grooves; track-rings ner sides, said track-rings having each a re movable sectionand engaging the bodies of Within the grooves of said rollers on their in 1 on the sleeve, said rooves bein the spacing-rollers Within the grooves; an inrollers intermediate the bearing-rollers having grooves therein registering with. and straddling all the flan es of the inner member; said grooves being 0' a depth to permit the spacing-rollers to engage the flanges and be supported thereby but not to permit of the spacing-rollers contacting with the inner member at any other point; means to hold said rollers together upon said inner member; and an outer member adapted to slip over the bearing-rollers and be supported thereby.

3. In an .antifriction-bearin the com bination of a hub an axle provi ed with a keyway; a key in said keyway; asleeve'ha-ving a keyway therein onsaid axle, said sleeve having a plurality of separated annular flanges near the'ends thereof, each flan e having aremovableportion, saidflsleevea so having an aperture at each end thereof which registers with the flanges; bearing-rollers having grooves therein registering with the flanges deeper than the height of said anges spacmgq'ollers intermediate thebearing-rollers', said spacingrollers having grooves. in the ends thereof .ada ted to fit over the flanges of the sleeve,

sai spacing-rollers being supported by said flanges out of engagement with the-slecve excep't at the fiangesand out of'engagement with the hub; insertible sections for said flanges, said insertible' sections also filling said apertures in'said'sl'eeve'; and retaining rings in the grooves in said rollers, said rings engaging thespa'cin -roll'ers within thegroove but not engaging t e bearing-rollers within the grooves.

In witness that I claimthe fore oi'ngli have hereunto subscribed my name tl is 12th day of October, 1905.
